You may know about the male pill (also known as male oral contraceptives), so that pills have been used since the middle of twentieth century ('60s), but most of them are still not available for public using up. It's very interesting about male pill description that one difference of the male pill purposes similarly to the oral contraceptive for the women is well known as the Pill: female and male pill apply hormones that synthetically modify the chemical balance of the body and avoid the gametes' maturation, that's why that the female doesn't ovulate (even if woman still menstruates) and the semen of the man doesn't include viable sperm. Contrasting to the pill for women, the male pill products may or may not have placebos because of the fact that the reproductive system of the man is not cyclical naturally. There are a lot of substances (for instance gossypol) that inhibit spermatogenesis undesirable side effects and the most important of them is the permanent sterility, which leads to the continued unavailability of the male pill. The Tripterygium wilfordii plant is working out researches as a promising source of candidate for chemical (as opposed to hormonal) contraception. Nowadays male pill development achieved that level when special variation of the male pill would block the protein of Cs, which is answerable for activating cell's tail (flagellum) of sperm, which helps them to move. In the case of using this technique, body will still create the sperm, but the sperm will be incapable to reach the egg because of the motility's lack. The most popular method of contraception now is using the condoms. Before the early to middle 80's, condoms as a medicine tool were low profile, undervalued products. Pregnancy's avoidance was condoms primary use. As you may know, condoms' function in helping to prevent STD's (sexually transmitted diseases). Even though they were recognized since Roman times, it wasn't a most important consideration among the society. The AIDS's (Acquired Immunodeficiency Syndrome) arrival, together with STD's increased incidence generally as well as the need to publicize avoiding infection effective means, resulted in a much more open discussion of sexual matters. The history of condoms has several periods including time of condom failure. FHI study in 1994 reported that the majority of condom users seldom experienced breakage of condom, at the same time as a the World Health Organization study reports that condom has 97% of effectiveness and some other studies have indicate it at approximately 80%. As you may know, the main cause for breakage, above and beyond misuse, is damage from rings, teeth, and fingernails or vain application. Some reports in the United Kingdom state that condom breakages occur only in 0.3% of the use time. Because of the fact that the most failures of condoms are due to misuse, several researchers suggested sex education for different age categories that includes condom use explanation.
